摘　　要：介绍了基于"平衡重建"反演模式的在线分析与在线显示平台EFIT。通过基于套接字(socket)的异构平台通信机制,实现了不同平台间的大数据量传输。用有限状态机描述服务端来管理节点,用群集系统的若干工作节点实现并行化计算,完成整个放电过程的位形重建通常只需要约1min的时间,能够满足(等离子体放电)间隔期间"在线显示等离子体平衡位形"的要求。利用该异构平台间通信模型,可将Linux平台下EFIT的运行结果,在Windows环境中在线地分析利用。An online analysis and online display platform EFIT, which is based on the equilibrium-fitting mode, is inducted in this paper. This application can realize large data transportation between inhomogeneous platforms by designing a communication mechanism using sockets. It spends approximately one minute to complete the equilibrium fitting reconstruction, by using a finite state machine to describe the management node and several node computers of cluster system to fulfill the parallel computation, this satisfies the online display during the discharge interval. An effective communication model between inhomogeneous platforms is provided, which could transport the computing results from Linux platform to Windows platform for online analysis and display.
